1. Purpose and Scope

This document is a full description of the serial communication protocol of the Allflex Stick

Reader with software version 0.46. It is intended for Allflex internal use only.

2. General Issues

The reader acknowledges every valid received character by looping it back to the sender. Invalid

commands or parameters are responded with an error code. The type of handshaking supported is

software controlled XON/XOFF.

Hexadecimal values from A to F can be entered either in upper or lower case.

All serial commands using parameters can be interrupted without changing the options by sending

the ESC character.

3. ASCII Protocol

3.1. Unrequested Transmission Messages

3.1.1. Turn-On Initialization String

Upon powering the reader on, the unit sends as an initialization string <STX><CR>

followed by a line feed character <LF>.

3.1.2. Transponder Identification Codes

There are several ID-Code string formats. The options are user selectable.

With all options enabled, a typical ID-Code will be transmitted in the following

format:

#T*RRRRR*D*EEEE*IIIIIIIIIIII<CR><LF> .. decimal

#T*RRRR*D*EEE*IIIIIIIIII<CR><LF> .. hexadecimal

,where:

# = Initial Character (“#”, “L”, “X”, “G” or none)

T = Tag Type Code (ALLFLEX

type, TIRIS

* = Field Delimiter (is either a comma, a semicolon, a space, a tabulator or

none)

R = Reserved Field (optional, available for ISO tags only 5 decimal or 4 hexadecimal figures)

D = Data Block Flag (optional, available for ISO tags only 1 decimal figure)

E = Extended Code (optional, Country or Manufacturers Code of ISO coded transponders with 3 decimal or

hexadecimal figures, Application Code of HDX-Industrial transponders with 4 decimal or 3 hexadecimal

figures)

I = National Identification Code (ISO tags: 12 decimal figures or 10 hexadecimal figures. HDX-Industrial tags:

16 decimal figures and 13 hexadecimal figures)

<CR> = Carriage Return (=0Dh)

<LF> = Line Feed (=0Ah)
